CROSS-REFERENCE TO RELATED PATENT APPLICATIONS

[0001] This patent application claims the benefit of priority to U.S. Provisional Patent Application No. 60/457,491, filed Mar. 25, 2003, and entitled “Mounting Foot for Light Bar,” which is incorporated in its entirety herein by this reference.

FIELD OF THE INVENTION

[0002] This invention pertains to signaling systems for emergency vehicles and more particularly, is directed to warning light assemblies for mounting to emergency vehicles.

BACKGROUND OF THE INVENTION

[0003] Emergency vehicles such as police cars, ambulances, fire trucks, etc. typically have a signaling system including audio devices, such as sirens or speakers, and visual indicators, such as warning lights. One common type of warning light assembly for emergency vehicles is a light bar. A light bar can include a plurality of lights that are enclosed in a common housing. Different types of lights, such as stationary, strobe, oscillating, and rotating lights, as well as a speaker or siren can be packaged in a given light bar to provide a variety of different signaling options.

[0004] A light bar is typically mounted to a flat surface of the emergency vehicle, such as a roof surface, for example, using bolts that extend through the light bar to the interior of the vehicle and that can be secured thereto via washers and nuts.

[0005] Current light bar designs commonly make use of multiple, stacked lighting levels. Through the use of different levels, warning lights, such as flashing, rotating, or strobe lights are disposed in a level of their own, while other auxiliary lighting, such as takedown lights, alley lights, and directional indicators are disposed in a separate level. Through the use of this multi-level approach, devices within one level do not adversely affect the visual performance of other levels. The minimum height of a light bar using this scheme is limited based on physical limitations of the devices within each level and the stacking of each layer upon the other. Additionally, to reduce the conspicuity of a vehicle while not involved in an emergency situation, it is desired that a light bar have as low a profile as possible. The use of multi-layered light bars limits the height to which a light bar can be lowered while still maintaining adequate functionality.

SUMMARY OF THE INVENTION

[0006] The invention provides a mounting foot for use with a light bar. A signaling assembly can include a light bar and a pair of mounting feet in accordance with the present invention. The light bar can be secured to the mounting feet via a plurality of fasteners. The mounting feet can be connected to a vehicle, such as an emergency vehicle, via conventional methods, such as, roof straps. The mounting feet serve to attach and space the light bar off the roof of the vehicle while providing a platform for the mounting of components, such as, auxiliary lights, for example.

[0007] Each mounting foot can include a base, which can have a support portion, a contoured portion, and a pair of compartments; a pair of covers removably mounted to the base to enclose the compartments; and a roof strap secured to the base. A pair of seals can be associated with each compartment to seal the interior of the compartment. Each compartment can house a signaling device, such as a lamp assembly. Each cover can be made from a translucent material to allow a lamp assembly housed within the respective compartment to emit light therethrough. Each mounting foot can be disposed near the outer side edges of the roof. The contoured portion can be configured to substantially conform to the crown in the roof of the emergency vehicle to allow the mounting foot to be seated on the roof of the vehicle and to utilize more available space for the mounting of components, such as auxiliary lighting devices.

[0008] The invention allows for a reduction in the overall height of the light bar while maintaining the advantages of a multi-layered light bar. By mounting components, such as auxiliary lighting, within the light bar mounting feet, the area between the light bar and the vehicle roof fulfills the function of an auxiliary signaling layer while allowing the overall height of the light bar to be reduced.

[0093] Referring to FIG. 63, another embodiment of a light bar 810 is shown. The light bar 810 can be substantially similar to the light bar shown and described in U.S. Pat. No. 5,884,997 to Stanuch et al., which issued on Mar. 23, 1999. In other embodiments of the signaling assembly, the light bar can be similar to the light bar shown and described in U.S. Pat. No. RE36,245 to Stanuch et al., which issued on Jul. 6, 1999. In yet other embodiments, the signaling assembly can include a light bar commercially available from Federal Signal of Oak Brook, Ill., such as one form the group including multi-level light bars, such as those marketed under the trade names VISTA Strobe, VISTA Halogen, and CUDA Spectre™, v-shaped light bars, such as those marketed under the trade names Premium Vision®, Smart Vector®, and Vector®; and single-level light bars, such as those marketed under the trade names Jetstream, JetStrobe Plus, Arjent™, Raydian™, and StreetHawk®, for example.

[0094] The light bar 810 shown in FIG. 63 is a multi-level light bar and has a housing 822 with a generally elliptical shape and a plurality of lights disposed inside the housing. The light bar 810 can be mounted on the emergency vehicle by means of the mounting feet, with the lengthwise direction of the light bar transverse to the forward direction of the vehicle.

[0095] In the illustrated embodiment, the light bar 810 has three sections, including a left side section 826, a right side section 828, and a center section 830. Another center section can be added to the light bar to allow incorporation of more lights in the light bar. Each section of the housing has a set of interfitting upper and lower shells which form a closed container. Thus, the housing includes upper shells 832, 834, 836, and the corresponding lower shells 838, 840, 842. The upper shells join the respective lower shells at a seam which surrounds the light bar. The lights in the light bar 810 are arranged in two tiers, one above the seam and one below the seam, to provide a variety of warning functions.

[0096] The upper and lower shells of each section interfit to form a substantially sealed container for protecting light fixtures mounted therein from the elements in the environment. The shells are preferably molded of a substantially transparent, high-impact plastic material, such as polycarbonate, for example, and are preferably clear, although they may be colored, or certain portions of the shells may be made opaque to prevent light emission in certain selected directions.

[0097]FIG. 63 shows the basic structural components of the light bar 810 without the lights mounted therein. As illustrated, the housing includes three sections 828, 830, 826 with upper shells 832, 834, 836 and lower shells 838, 840, 842, respectively. The lower shells 838, 840, 842 of the three sections are rigidly secured to a structural support member for structural support. In the illustrated embodiment, the structural support is an extruded beam 844 which has a length shorter than the overall length of the light bar. The beam 844 can be made from any suitable metal, such as, aluminum, for example. The structural rigidity of the light bar is further enhanced by the use of interlocking ribs 846 disposed on the opposing sides of adjacent lower shells.

[0098] The light bar can have a modular construction which is achieved by the use of trays with cells for mounting lights. As illustrated in FIG. 63, the side sections 826, 828 have side trays 850, 848, respectively, disposed therein in the recesses of the lower shells 838, 842 around the ends of the beam 844. The center section 830 has a front tray 852 and a rear tray 854 disposed in the recesses in the lower center shell 840 on the two sides of the beam 844. The trays are preferably molded of plastic.

[0099] The trays 848, 852, 854, 850 are attached to the respective lower shells 838, 840, 842. Each tray 848, 852, 854, 850 can include a plurality of vertical dividers which define an associated plurality of light cells (indicated by arrows in FIG. 63) for receiving standardized light fixture components, for example. The thickness of the trays is such that the tops 856, 858, 860, 862 of the trays when mounted in the lower shells have a height that substantially matches that of the seam of the housing. The tops of the trays separate a lower tier of lights which is below the seam from an upper tier of lights above the seam. The tops of the trays also provide a platform for mounting lights on the upper tier.
